IMIROVED IUENAOEIOE .-EEDUGING METALLIO ontaI TO ALL lWHOM IT MAY CONCERN:

Be it known that I, EUGENE WILLIAM NOHI, of Ripon, in the county OfFond du Lac, and State of Wis` censiti, have invented a new and useful improvement in Furnaces for Reducing Metallic Orcs; and Ido hereby declare thatthe following description thereof is full and exact, reference being had to the accompanying drawings, and to the letters of reference marked thereon. l

lMy invention consists in a novel construction of furnace for the use of gaseous fuel in treating metallic ores for obtaining the metals, and lin 'the combination therewith of a gas generator provided with a blast for i converting coal and other splid fuel into gas. In theA accompanying drawings--` Figurel represents my improved furnace, one side of the fire-chamber being removed in Orderto show the internal arrangement.

Figure 2 is a vertical section of the gas generator detached from the furnace.

In the construction of roy furnace, the fire-chamber A may be of any suitable eine and form,'made of rebrick or other suitable material. The bed or iioor of the furnace B ist@ be more on less inclined downward and outward from the centre, (where the'mass of ore is to be placed for heating) for the purpose of allowing the fused metal to dow away from the central heat and bc drawn off from the furnace without interrupting the blast.,` Under the bed of the furnace I have arranged a series of pipes or fines, @through which the smoke and draught pass, the direction of thedraught being indicated by the arrows in fig. 1. The upper part of the rechamber is provided with a hopper or feed-box, D, through which the coal or other solid fuel is introduced to the furnace. The furnacemay be filled with ore, as seen at E, until the top of the piles reaches the bottom of Athe feed-box D, which is to be kept full of ore, so that more ore will fall into the furnace as the pile below is melted away by heat. 1 l

The fuel intended to be used in my furnace is gaseous, the same being prepared in a suitable gas generator shown in iig. ,2. This fgas generator has a suitable {ire-chamber, E, into which coal or other solid' fuel is introduced and converted into gas, and an air-blast is connected therewith in order to control the rapidity of generating gas. From the generator the gas is conducted immediately to the furnace, entering at both` ends, by means of pipes F,'fig. Near these pipes, two other pipes G bring in a blast of air to facilitate the complete combustion of the gases. By the meeting of the two currents of gas and-air the hottestv ilames are directed upon the pile of ore. l y l l A By the above arrangement the amount of ore supplied to vthe furnace depends upon-the quantity reduced, and the consequent sinking of the pile of ore in the furnace; and the quantity of fuel or gas supplied to the furnace is under the control of the operator by means o f the blast in the generator.` Consequently thewhole operation is completely under control theore being quickly reduced to metal, and the-latter removed without overheating or burning. And there is little chance of chilling the furnace.

I am 'aware that gas has been used as fuel inA furnaces for reducing metallic ores, therefore Ido not broadly claim such use. Neither do I confine my invention tothe above-described form of furnace so' long as the saine results are obtained.

Having fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is i i 1. A furnace provided with short pipes or passages for introducing the gas, (het from the generator,) into the furnace, and also with a blast of air, the meeting currents of gas and air directing the dames upon the ore, substantially in the manner and for the purposes set forth. y

2.- I claim the raised centre of the bed of the furnace for supporting theore and allowing the fused metal to iiow awa-y from the central heat, 'and be drawn off Without being overheated or burnt, substantially as described.

3. 'I claim a gas generator provided with a blast, in combination'with a furnace for burning the gas before. cooling, substantially in the manner and for' the purposes specified. A

EUGENE WILLIAM NOEL.
